' JOHN STEVENS MOREA, OF BAYSIDE, LONG ISLAND, NEW YORK, ASSIGNOR TO PORT- ABLE LIGHT COMPANY, INC., OF NEW YORK, N. Y., A CORPORATION OF'NEW YORK PORTABLE SEAR'GHLIGHT Application filed. February lii, i927. Serial No. 169,159.

This invention relates to improvements in portable electric search lights, and particularly those of a high power adapted for a variety of uses such as for automombiles, boats, fire companies, public utility corporations, signaling lights, etc. The invention comprises a suitable reflector for projecting the rays of light which is adj ustably mounted upon a casing containing any desired source of electric current.

It is an object of this invention to provide a portable electric search light of high power and long life mounted on a suitable support, the source of current for the light being removably retained in the support, at a lower.

cost than possiblewith prior construction. It is a further object of this invention to provide a portable electric search light comprising a reflector and a rearwardly extending handle in the end of which is provided an electric control switch.

Another further object of this invention is to provide a portable container for use with a'standard reflector mounting, comprising a box shaped receiver with a hinged end, the receiver adapted to removably retain a storage battery, and being provided on its top with a suitable means for attaching the reflector mounting.

It is a further object of this invention to arrange the handle of a reflector mounting superposed on a battery box receiver so that the entire device may be carried by the handle without changing the desired angle of light beam. Other objects of the invention will more fully appear from the following description and the accompanying drawings which illustrate a preferred embodiment of the invention, and will be specifically pointed out in the annexed claims.

In the drawings- 7 Figure 1 is a perspective view of my port- 1 able electric search light.

Figure 2 is a side elevational view partly in section through the light and battery box.

Figure 3 is a detail on the line 33 of Figure 2.

Figure 4 is a detail view partially cut away to show the construction of the sleeve fastener. V

The light mounting 1 is preferably made as a unitary casting comprising the front por-' tion to which the reflector 2 is "suitably attached as will be later described, the rear portion which isturned down to receive the hollow carrying handle? preferably made of hard rubber and integral therewith and an extended stem 4 to be adj ustably attached to the battery case 5.] i I k The battery case '5, preferably -made of sheet steel and welded-along the edges,lis'of such proportions as to-receive. and retain the" storage battery 6,, which maybe removed throughthe door 7 hinged or bolted in place in any desired manner. This case also has abracket 8, cooperating with the, end of the stem t to adj ustably and pivotally attach the reflector, mounting and 'handl'e thereto. 'It is to be noted that the case 5 is separate from the conventionally known battery box con"- tainingthe cells of the battery 6,'and;sealed thereto. t 1.

The cylindrical hollow handle 3and mount ing are provided with a suitable tubular sock et 9, preferably of the bayonet type construction, and which supports thelight source or bulb and socket being electric bulb 10, the longitudinally mounted I for adjustment by the adjusting screw 11 whereby any desired focus of the bulb relative to the reflector may be arranged; I l v The socket 9 is connected by meansof the necessary wires to the toggle switch 12p'referably" conveniently, reposing within finger reach in the'endof the handle 3, and to the terminalsof'the battery 6, the parts. of the wire subject to abrasion or contact with ex terior elements, being covered with 'a heavy rubber tube for protection. "It is clearly used, the object being to allow for insertion of a bulb 10 and to provide a means to keep dust, dirt and water from marring thereflector. v r

The bracket 8 is provided with a bolt 8 acting both as a pivot and as an adjusting means so that the reflector and mounting may be swung through any desired arc and may be retained in such position by merely tightening the bolt 8*. i 7

Figures 3 and 4: show thefend and side views of the threaded sleeve 16 which is flanged at the head to cooperate with the depressed portion of theback of the reflector. The screw threaded portion is adapted to be inserted through the hole in the reflector and screwed into the mounting 1. This arrange ment is a preferred one as it allows forinterchangeability of parts and ready removal in case of damage to the. body or surface of the reflector or other, parts with the use of a minimum number of parts.

The storage battery 6 used in this portable light, as will be noticed,is used for no purpose other than its proper function; the supply of electric energy. By thus limiting. it

the construction may be very cheap,light in weight and of a standard form in common.

use. For all purposesof support and for pro-. tection, as well as to present a neat appear ing portable light, the sheet steel case is used. The ready removability of the battery to and from the case, allows a continuous service with the quick substitution of one battery for a recharged one. .Such organizations as a fire. company are therefore adequately equipped: witha high powered light in portable form;

operable under any and allemergencies', with the only expense of maintenance, the illSig recharglng the batteries as fic-a t cos f needed.

It will be understood that the. embodiment oi the invention disclosed herein is illustrative and not restrictiveand that various changes in form, construction and. arrangement of partsv may be made within the spirit and scope of the appendedclaims.
